client: pdf-gen: improve adding bottleneck info to pdf
* Check if the bottleneck is in the current view to add its info to the exported pdf and the pdf filename, this avoid wrong filename and wrong info in pdf in case view has been changed to another location.
* Set the bottleneck to print after moving to it in map.
